Myrtrimonium Bromide ●
TL;DR. This ingredient is a cationic surfactant used mainly as an antistatic and conditioning agent, especially in hair-care formulas. It can also support emulsification and has antimicrobial activity in some systems.
What does Myrtrimonium Bromide do in a cosmetic formula?
This ingredient is a cationic surfactant used mainly as an antistatic and conditioning agent, especially in hair-care formulas. It can also support emulsification and has antimicrobial activity in some systems.
Is Myrtrimonium Bromide clean?
From a clean-beauty perspective, this ingredient has friction because it is a synthetic quaternary ammonium compound with rinse-off concentration limits and aquatic-impact concerns. It may also be irritating at higher levels, so its acceptability depends strongly on dose and product type.
Is Myrtrimonium Bromide sustainable?
This material is typically petrochemical-derived or partly petrochemical-derived rather than a renewable botanical input. It is water-soluble and can bind strongly to sludge and surfaces, and its aquatic profile is less favorable than many readily biodegradable plant-derived surfactants.
Is Myrtrimonium Bromide COSMOS-approved?
This ingredient is not a strong fit for COSMOS natural or organic standards and is generally treated as a non-aligned synthetic cationic surfactant. From a Green Chemistry view, its synthetic route, charged persistence behavior, and aquatic-impact profile are the main drawbacks.
How does Myrtrimonium Bromide work chemically?
The molecule is a permanent cationic quaternary ammonium salt with a long saturated alkyl chain, which lets it adsorb onto negatively charged hair and skin surfaces. It is stable across typical cosmetic pH ranges, incompatible with many anionic surfactants, and used at low conditioning levels because performance and irritation potential are concentration-dependent.
